Stayed here with a group of friends for the Austrian Ironman. Perfect location five minutes from the airport, fifteen min drive from Klagenfurt town which is beautiful. The family were fantastic and very welcoming. Two daughters who did loads of baby sitting and were just brilliant. The hotel itself a piece of history - absolutely beautiful all the rooms very original. Swimming pool great, and the grounds perfect for small kids. They only serve breakfast which was great - though it would have been better had they served lunch and / or dinner as well esp for the kids. However, there is an italian not far that was very good (called Michelangelos) and they could accommodate over twenty of us at short notice two nights in a row. Small village five min walk away with a couple of restaurants which were ok if you like fried chicken in breadcrumbs and chips.
Would definitely go there again!
